Experiment of 60 simply supported concrete beams loaded by equal amplitude fatigue loading was studied. These beams were reinforced by cold-rolled deformed steel bar and were with different reinforcement ratio of 0%, 0.29%, 0.487%, 0.934% and 1.946%. The fatigue failure types of the beams were fracture failure, bending-tensile failure and shear-compression failure. Aimed at the different fatigue failure types of the beams, the failure causes are analyzed. A concept of critical reinforcement ratio is offered. The concrete beams reinforced by adequate cold-rolled deformed steel bar have well resisting-crack ability and ductility, and their fatigue lives increase remarkably. A fatigue equation taken different reinforcement ratio into account is presented, which can be used for design of reinforced concrete pavement.
